Abstract
The utility model relates to a wastewater treatment system, which comprises a preheater, an MVR (Mechanical Vapor Recompression) evaporator, a DTB (Draft-Tube-Baffled ) crystallizer and a centrifuge. In the sewage treatment system, the high-efficiency energy-saving MVR evaporator is adopted to replace a traditional single-effect evaporator, thus improving the thermal efficiency and reducing the operating cost; and at the same time, after secondary vapor generated in a flash chamber of the DTB crystallizer is compressed by the MVR vapor compressor and the temperature is raised, materials in the evaporator can be heated, and the condensation water formed by condensing the secondary vapor can also be used to heat the material in the preheater, thus realizing reutilization of the waste vapor, and achieving the energy-saving and environment-friendly aim.
Description
Technical field
The utility model relates to a kind of Waste Water Treatment, relates in particular to a kind of Waste Water Treatment of recyclable inorganic salt.
Background technology
Wastewater from chemical industry is varied, and most severe toxicity are difficult for purifying, and certain summation is arranged in vivo, have obvious aerobic in water body, easily make water quality deterioration, if directly discharging must bring serious problem of environmental pollution.Therefore, in chemical process, the wastewater treatment operation becomes requisite operating unit.For high density inorganic salt waste water, because salt is not volatile, if adopt single-effect evaporator to reclaim inorganic salt by transpiring moisture, must consume a large amount of energy, cause cost for wastewater treatment high.
Summary of the invention
The purpose of utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of energy-efficient Waste Water Treatment is provided.
in order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise preheater, the MVR vaporizer, draft tube baffle crystallizer and whizzer, it is characterized in that: described preheater top is by pipeline communication MVR vaporizer and recycle pump, described MVR vaporizer top exit end is connected in the inlet end of draft tube baffle crystallizer flashing chamber side by pipeline, described draft tube baffle crystallizer top and MVR vaporizer top are connected with a MVR vapour compressor between one side pipe road, draft tube baffle crystallizer lower end two device for cleaning pipelines are crossed a magma pump and are formed circulation loop, have a bypass line on described magma pump and crystallizer pipeline and be connected whizzer, connect a condensed water receiving tank between described preheater and MVR vaporizer, control flow by condensate pump.
The utility model has the advantage of: in this Waste Water Treatment, adopt energy-efficient MVR vaporizer to replace traditional single-effect evaporator, its thermo-efficiency is high, and running cost is low; Simultaneously, secondary steam in the generation of draft tube baffle crystallizer flashing chamber, after compression heats up through the MVR vapour compressor, can heat material in vaporizer, and the condensed water that the secondary steam condensation is got off, also can be used for the heating of material in preheater, realized the recycling of exhaust steam, reach the purpose of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structural representation of Waste Water Treatment in the utility model.
Embodiment
As accompanying drawing as can be known, comprise preheater 1, fresh feed pump 2, condensed water receiving tank 3, condensate pump 4, MVR vaporizer 5, vapour compressor 6, draft tube baffle crystallizer 7, recycle pump 8, magma pump 9 and whizzer 10.
described preheater 1 top is by pipeline communication MVR vaporizer 5 lower ends and recycle pump 7 left ends, described MVR vaporizer 5 top exit ends are connected in the inlet end of draft tube baffle crystallizer 7 flashing chamber sides by pipeline, described draft tube baffle crystallizer 7 tops and MVR vaporizer 5 top is connected with a vapour compressor 6 between one side pipe road, draft tube baffle crystallizer 7 lower end two device for cleaning pipelines are crossed a magma pump 9 and are formed circulation loop, have a bypass line on described magma pump 9 and draft tube baffle crystallizer 7 pipelines and be connected whizzer 10, connect a condensed water receiving tank 3 between described preheater 1 and MVR vaporizer 5, control flow by condensate pump 4.
During work, material advances preheater 1 preheating through fresh feed pump 2, utilizes the condensed water of 3 li of condensed water receiving tank to add thermal material; Send into vaporizer 5 through pre-warmed material and utilize the secondary steam indirect heating continue to heat up, become water of condensation after the secondary steam condensation and send into condensed water receiving tank 3 and store for future use; The material of heating is sent into the flashing chamber of draft tube baffle crystallizer again, and owing to be negative pressure in flashing chamber, material rear moment of coming in evaporates, and most of water becomes secondary steam, through vapour compressor 6 compression intensifications, then sends into MVR vaporizer 5; The interior unevaporated material of draft tube baffle crystallizer 7 mixes in crystallizer and forms stable magma district, utilizes the conveying of magma pump 9, the crystalline salt of high density is sent to whizzer 10 carries out centrifugation, and remaining returns to draft tube baffle crystallizer 7 and continues growing the grains; Material returns to remaining product to 5 evaporations of MVR vaporizer through recycle pump 8 after treatment and purifies.
In said process, the secondary steam that draft tube baffle crystallizer produces namely can be used for vaporizer and adds thermal material, can be again preheater heat is provided, and realizes the efficient recycling of heat energy, reaches the purpose of energy-conserving and environment-protective.
